I apparently have a wide selection of ammo with no guns for said ammo (includes 30.06, 9mm Luger, a metric ton of 22 long rifle bird shot), a Walther magazine (again, no gun for the mag), some weird 357 rounds with flat tips (like completely flat), some rounds that looks like the bullets are coated in a really hard plastic or ceramic (wtf?) and somehow have M1 blanks (says so right on the box). And brass. A lot of empty brass.
Or maybe it might be easier if I post pics here and you knowledgeable people could comment?

You should be able to find lists for other cartridges as well. It is almost too comprehensive, however, since it will list just about everything ever made and not necessarily those that are readily available for purchase (which is I assume what you're after).
